Do not set DW_AT_inline incorrectly on all functions.

Do not remove formal parameters when a previous DIE has been found.
Instead, augment the missing bits later.

[NDS32] No need to take padding into consideration in Andes ABI2 because
        we can pass arguments in registers for variadic function.

  -- By default GCC uses must_pass_in_stack_var_size_or_pad for TARGET_MUST_PASS_IN_STACK.
     For Andes ABI2, the data layout in memory will be incorrect when calling variadic function
     under big-endian configuration.

	for TARGET_MUST_PASS_IN_STACK.

From-SVN: r214869

        partially in registers and stack.

  -- This is needed if we would like to pass variadic arguments via registers
     that are pused on the stack by callee.  So that va_arg() can access
     arguments continously in memory.

	* config/nds32/nds32.c (nds32_arg_partial_bytes): New implementation

[NDS32]  Emit stack push instructions for varargs at prologue stage and
         emit stack adjustment instructions for varargs at epilogue stage.

  -- Note that we do not need to handle it in v3push/v3pop prologue/epilogue
     expanding because we do not apply v3push/v3pop for variadic function.

  1. We have caller prepare nameless arguments in the way of calling a normal function.

     e.g. Assume a function: void va_test (int n, ...);
          When calling "va_test (6, 11, 22, 33, 44, 55, 66);",
               r0    <- 6
               r1    <- 11
               r2    <- 22
               r3    <- 33
               r4    <- 44
               r5    <- 55
            [sp + 0] <- 66

  2. Note that we DO NOT handle it for TARGET_HARD_FLOAT case.
     The TARGET_HARD_FLOAT should push all the nameless arguments into
     stack and GCC is able to take care of them itself.
     In addition, we have not implemented hard float on trunk yet.
